im hoping someone here can help me with this. ive got an 05 ss/sc and have had a pioneer 940mp in it for a few years, along with the pac module and swi module for steering wheel controls (infered version as the deck doesnt have a remote input) and everything had been working fine. ive now changed my deck out for a pioneer avh8400, and ive changed to an axxess aswc module for steering wheel controls.

im having problems getting the aswc to work correctly. i followed the program instructions, it auto detected and some buttons worked. i went through the manual key asign portion and i can get everything to work correctly except the volume control. the volume up works as it should, however the volume down button turns the volume up as well. i went through the programming a number of times with no change, have gone through the troubleshooting and cant come up with anything. i did use the correct wire, i have rechecked that. im certain its not the steering wheel controls themselves, they worked just fine with the old swi module.

anyone had a similar issue, or know what i need to do to fix it?

 

when doing the wiring is there anything that needs to be cut or removed?

 

no the module is pretty straight forward. it has 12 wires on it, however use depends on vehicle. it has a ground, switch power (hooked to pac interface module acc. voltage output), and the steering wheel control input (from the wheel) goes to the yellow/green wire on pin 3 of the module. plug the mini stereo connector into the deck and thats it.

like i said, it all works, except for volume down.

 

hmm try contacting metra support??? the only reason i asked is because ive seen a similar issue on PAC swi interfaces but they have a wire thats looped into the unit that needs to be cut for certain vehicles.

 

Sharkey- Did you ever get an answer to this question?
I'm having what sounds like the EXACT same problem (Volume Down button making the volume go up).
